One of my absolute favorites: the ten-pager in which Huey, Duey and Louie persuade Donald in starting a singing career. However, Donald soon turns to being a musician- a very bad one- who keeps using louder and bigger instruments every time, driving HD&L crazy.

Easy one! You gave it away with the name 'Pleasant Valley'. The story in which Donald, HD&L have a farm on a hill just outside Pleasant Valley where they're holding chickens, for the eggs. The prices sink however, and they're forced to keep all the eggs in storage until the price goes up again. Then one day, there's a little earthquake, and Donald's barn collapses, and all the eggs are rolling down the hill, turning Pleasant Ville into Omelet Ville.
